Hi i am trying to use adding to scene , it adds the new model but the first one disappears even when i make sure it is visible in the layer panel.
Also i tried to use the lasso freehand trim , in places it just trimmed it but in a very untidy way the meash around it is kind of broken
Would really appreciate your help thanks!
To the first problem:
One of your objects is most likely way too small or way too big.
In the scene, select the object you don’t see - then select the Gizmo tool.
Now you can scale.
You can also just add a new sphere, then you can compare the sizes.

With the Trim Tool there can sometimes be problems…
You could post a screenshot, with wire frame on.
